4.6 FORWARD / REVERSE SPEED ______________________________________________
Forward and reverse speeds are adjusted at the traction
pedal. Set forward speed before adjusting reverse.
To adjust forward speed:
1. Make sure drive pump has been set to neutral and
engine throttle is adjusted correctly.
2. Start engine and check forward travel speed with
engine at full throttle and tractor in two wheel drive
(2WD). Forward transport speed should measure 10
mph (16 kph)
3. Stop engine. To adjust speed, disconnect eye bolt (K)
from pedal and loosen jam nut. Turn eye bolt in to
reduce speed, out to increase speed. Tighten jam nut
to hold adjustment in place and connect eye bolt.
4. With traction pedal in neutral, check position of neutral
switch
(J). Adjust switch up or down so pointer (M) on
traction pedal bracket is centered over it. When
adjusted correctly lamp 5 on controller will light when
ignition switch is turned to on.
5. Start engine and check speed. Repeat procedure until
10 mph (16 kph) forward transport speed is attained.
To adjust reverse speed:
1. Set forward speed.
2. Start engine and check reverse travel speed with
engine at full throttle. Reverse speed should measure
3.5 mph (5.6 kph)
3. Stop engine. To adjust speed, loosen nut on reverse
travel stop bolt (L). Slide bolt forward in slotted hole to
increase speed, back to reduce speed. Tighten nut to
hold adjustment in place.

5.2 CONTROLLER LAMPS _____________________________________________________
The controller is a solid state device that monitors and
controls electrical functions. The controller receives input
signals from various switches and sensors throughout the
machine and transmits output signals to operate relays,
solenoids and warning lights. It controls and resets timers
and contains built in logic to control certain machine
functions.
Each input and output signal is displayed through lamps
located on top of the controller. A closed input switch
indicates an active circuit and will turn an input lamp on, an
open switch an inactive circuit and will turn a lamp off.
Outputs are active when their lights are on.
It is important to note that in some cases a lamp or group of
lamps must be on or off for a condition to be true. For
example, to start the tractor the Mow Switch must be off
(lamp 8 off) while the Neutral Start Switch (lamp 12), Brake
Switch (lamp 6) and Fuel Valve Hold coil (lamp 27) must be
on.
